1. Joint investment: Joint investment and portfolio investment are important measures to spread risks. Joint investment means that multiple venture capitalists jointly invest in the same venture enterprise, which is conducive to information sharing among venture capitalists, improving the accuracy of project selection, strengthening investment supervision, providing more value-added services, ensuring that the total investment of venture enterprises reaches a reasonable scale and improving the investment success rate.

2. Portfolio investment: Portfolio investment means that investors adopt various forms of portfolio investment strategies such as equity, creditor's rights, quasi-equity and guarantee according to the requirements of different development stages of the project to ensure the project's need for funds and reduce the losses caused by project failure.
